The Oceanic Emerald was described in 1871, the species is endemic to the Society Islands, where it occurs from areas near sea level to the higher areas at elevations of about 1000m.

The species is often seen flying 1,5 to 3 m above the ground along larger roads or in clearings within the forest.

The Oceanic emerlad is beautifully glossy bluish green colored, the wings are quite variable in their coloration, some being clear to a deep amber-like yellowish hue. [1]


The picture below, supposed to show this species, probably shows another species.


There appears to be another, up to now unnamed species of that genus inhabiting, that might be endemic to the island of Tahiti, where again it is apparently restricted to the higher altitudes. [1]
